Wow. *Glad I finally read this thread...I have that same plant, and I too was under the impression it was a tobiaca. *I must say, though, I did have some doubt because the pitcher shape doesn't seem right. *
Is anyone familliar with how tollerant this one is to lower humidity? *If it is, indeed, khasiana x ventricosa, one would assume it could be grown in fairly dry conditions (for a nep).
